Sure. The voltage would have to match (which it does) so no worries there.
the current ought to be less to not cause any problems. The old fan is
120mA (there's 1000 milliamps (mA) in an amp), so the new one draws half as
much power. It may well be half as strong, or it may be more efficient.
Either way, it'll function without blowing up something in the supply. It
may not, however, provide as much cooling. If you can find a fan that would
match both current and voltage, it'd be better.

| (...) I believe the new fan is more efficent (it's a high-quality Papst fan). The specs say it moves the same amount of air as the old one. Thanks for your advice! -chris (22 years ago, 9-Oct-02, to lugnet.off-topic.geek)
